Chatty, this is something I've been a bit worried about, not making the same moves as before, and being thought of (if not outright accused) as a cheat. But everyone is in the same boat, I've resigned a few games I know I lost the first time round, and I have had people also resign games I won... but if I have forgotten a game or not made moves I should have, then I would ask my opponents to tell me rather than stew on it! Its a genuine mistake (my memory isn't great!) and given a nudge I'll make the 'right' moves!
